1. Field of Invention
The invention herein relates to a safety driving equipment for a toddler's scooter, mainly to provide an auxiliary wheel, relative to the rear wheels of the scooter body, to the driving structure of a toy scooter to increase the safety area and regulating the location of the force center.
2. Description of Related Arts
As shown in
Referring to
Moreover, since the left and the right driving wheels 21, 22 are located close to a mid-portion of the scooter body 1, a head portion of the scooter body 1 is suspended with respect to the ground. Therefore, the scooter will easily be flipped over from the front especially when external force is exerted on the front portion of the scooter body 1 such as hitting to a curb or crossing a bump. Besides, when the rider sits close to a rear portion of the scooter body 1, which is also suspended with respect to the ground, the scooter will be flipped over from the back easily.
It is unreasonable to let a young child in a risky or unsafe situation. However, we have to tolerate the above mentioned suffering drawbacks until an improved scooter that can provide an absolutely safe for the rider to play with the scooter is developed.
A main object of the present invention is to provide a safety driving equipment for scooter, which can provide an absolutely safe scooter structure for a rider to avoid any unwanted flipping manner of the scooter.
Another object of the present invention is to provide a safety driving equipment for scooter, which comprises a safety wheel rotatably extended from a driving mechanism for supporting a front portion of the scooter body, so as to prevent the scooter body being flipped over from the front thereof.
Another object of the present invention is to provide a safety driving equipment for scooter, which comprises an anti-flip member affixed to a rear portion of the scooter body for reducing a vertical clearance between the rear portion of the scooter and the rear wheels, so as to avoid the scooter being flipped over from the back thereof.
Another object of the present invention is to provide a safety driving equipment for scooter, wherein the two rear wheels are further extended far apart from the scooter body for increasing the safety area of the scooter, so as to prevent the scooter being flipped over from the sides thereof.
Another object of the present invention is to provide a safety driving equipment for scooter, wherein no expensive or complicate mechanical structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for preventing the scooter being flipped over easily.
Specifically, the invention herein is consisted of an extended arm at the end relative to the driving wheels of the driving wheels of the driving mechanism; and a safety wheel capable of making universal rolling mounted lively at the end of the wheel arm. The driving mechanism is driven by a steering wheel through a transmission unit. Therefore, by moving around based on the transmission unit as the center and utilizing the relationship of the safety wheel relative to the rear wheels of the scooter body to increase the possibility of locating the force center in the regulated safety area.
To enable a further understanding of the objectives, the technological methods and the efficiency of the invention herein, the brief description of the drawings below is followed by detail description of the preferred embodiment.
Referring to
The scooter further comprises a transmission unit 11 having an upper control portion positioned above the scooter body 1 and a lower connecting portion extended underneath the scooter body 1, a steering means 12 affixed to the control portion of the transmission unit 11 for driving the connecting portion thereof to rotate in clockwise and anti-clockwise directions, a twister member 2 having a driven portion connected to the connecting portion of the transmission unit 11, and a pair of driving wheels 21, 22 spacedly and rotatably mounted to the twister member 2 wherein the two driving wheels 21, 22 are spaced apart from the driven portion of the twister member 2. Therefore, in order to drive the scooter, a rotating force must be applied on the steering means 12 to drive the twister to rotate in a clockwise and anti-clockwise manner.
The safety driving equipment comprises a supporting arm 23 frontwardly extended from the driven portion of the twister member 2 and a safety wheel 24 rotatably connected to a free end of the supporting arm 23 for supporting a front portion of the scooter body 1, so as to prevent the scooter from being flip over from the front thereof.
According to the preferred embodiment, the scooter body 1 has a receiving cavity wherein the two rear wheels 31, 32 are received therein via a wheel axle. In other words, the two rear wheels 31, 32 are operated within the receiving cavity of the scooter body 1.
Referring to
According to the preferred embodiment, the steering means 12 comprises at least a hand bar which functions as a steering wheel for a rider to drive the twister member 2 to rotate wherein the steering means 12 is capable of not only moving the scooter forwardly or backwardly but also directing the course of the scooter.
The transmission unit 11 is a shaft having a top end which is the driving portion of the transmission unit 11 connected to the steering means 12 and a bottom end which is the connecting portion of the transmission unit 11 connected to the twister member 2 wherein the transmission unit 11 is rotatably penetrated through the scooter body 1 in such a manner that the steering means 12 is arranged to drive the twister member 2 to rotate when a rotating force is applied on the steering means 12.
As shown in
Accordingly, the supporting arm 23 is integrally extended from the twister member 2 at the driven portion thereof and has a free end for rotatably connecting to the safety wheel 24.
The safety wheel 24, which is a free rotating wheel, comprises a vertical axle affixed to the supporting arm 23 and a wheel casing rotatably attached to a bottom end of the vertical axle and rotatably received a ball shaped rotating wheel in the wheel casing such that the safety wheel 24 is adapted to self-rotating 360 degrees with respect to the free end of the supporting arm 23. Therefore, when the twister member 2 is driven to rotate, the safety wheel 24 is capable of rotating with respect to the twister member 2, so as to prevent the safety wheel 24 being stunk when operating the scooter. The wheel casing further comprises a ball bearing encirclingly mounted thereto for enhancing the rotating wheel in a free rotating manner. Since the safety wheel 24 is frontwardly extended from the twist member 2 for supporting a front portion of the scooter body 1, the scooter will not be flipped over from the front thereof.
As shown in
Referring to
In order to drive the scooter forwardly, the driven portion of the twister member 2 must be positioned in front of the two driving wheels 21, 22, as shown in
Furthermore, the length of the supporting arm 23 is better limited within the outer rim of the scooter body. If too long, the burden of operation the wobble will be affected; if too short, then there is no functional meaning. In fact, the length should be the diameter of the actute movement of the safety wheel 24 no longer than the wheel base between the two rear wheels 31, 32.
Referring to
As shown in
In order to reduce the size of the scooter, the scooter body 1' can be shaped slimly. However, the rear wheels 31, 32 are received in the receiving cavity of the scooter body 1 in the first embodiment. When reducing the width of the scooter body 1, the width of the rear wheels 31, 32 will be reduced as well, which may cause the scooter flipped over sidewardly.
In order to lengthen the distance between the two rear wheels 31', 32', the scooter body 1' further comprises a pair of wheel arms 51', 52' outwardly extended from two sides of the scooter body 1' for rotatably connecting the two rear wheels 31', 32 respectively. As shown in
Therefore, the invention herein provides a safety driving equipment for the scooter and meets new patent application requirements and is hereby lawfully submitted to the patent bureau for review and the granting of the commensurate patent rights.
